Description

Technical Field

[0001] This utility model relates to the field of plaster technology, specifically to a plaster packaging machine and its production device. Background Technology

[0002] In the current production of adhesive plasters, individual sachets have become the standard process to ensure product stability, hygiene, and portability. This process typically involves multiple steps, including coating and lamination, precision die-cutting, single-piece separation, bagging, and heat sealing. However, the downstream packaging process still faces significant efficiency bottlenecks, hindering overall capacity and cost optimization.

[0003] The current method of bottling plasters requires first removing the pre-made bag, then placing the plaster into the pre-made bag, removing the air from the pre-made bag, and finally heat-sealing it. This process, involving multiple steps such as removing the bag, opening the bag, filling, removing air, and sealing, severely restricts the bottling efficiency. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this invention provides a plaster packaging machine that can efficiently package plasters.

[0005] This utility model discloses a plaster packaging machine, including a frame and a conveying mechanism, an unwinding mechanism, a heat-sealing mechanism, and a cutting mechanism arranged sequentially on the frame along the material flow direction. The conveying mechanism includes several parallel conveyor belts, with side guards on both sides of the frame to constrain the material. Limiting protrusions are spaced along the length of the conveyor belts to push the material and maintain spacing. The unwinding mechanism includes a set of pressure rollers, a first unwinding roller, and a second unwinding roller. The pressure rollers are located at the discharge end of the conveyor belts, and the first unwinding roller is located above the pressure rollers for unwinding the upper packaging film. The second unwinding roller is located below the pressure rollers. Below, the lower layer of packaging film is unwound. The two layers of film are joined by pressure rollers and initially bonded with adhesive from the conveyor belt. The heat-sealing mechanism is used to heat-seal the four sides of the bonded packaging film. The heat-sealing mechanism includes a frame with two parallel guide rails horizontally arranged on the frame. The frame is slidably connected to the guide rails via a slider. A lead screw is horizontally arranged between the two guide rails. Both ends of the lead screw are fixed to the frame via bearing seats. Nuts are fitted on the lead screw and fixedly connected to the frame. A servo motor connected to the lead screw is mounted on the bearing seat and electrically connected to a controller. The rotational motion of the lead screw is converted into the linear motion of the frame. The linear motion is achieved by the forward or reverse rotation of a lead screw, which propels the frame in a reciprocating motion. During this reciprocating motion, the frame, driven by a servo motor, must precisely move along the guide rail to each predetermined heat-sealing station and move at the same speed as the material. A heating plate is horizontally fixed on the upper side of the frame, and its lower end face has several rows of rectangular annular protrusions. The number of rows of protrusions is equal to the number of conveyor belts, and their positions correspond one-to-one. A cylinder and several guide pillars are vertically installed on the lower side of the frame. A sliding guide sleeve is fitted on the guide pillar, and a pressure plate is fixedly connected to the guide sleeve and connected to the piston rod of the cylinder. The cylinder is controlled by a cylinder control system to extend and retract. The frame moves to... During each predetermined heat-sealing station, as the material moves at the same speed, the cylinder-driven pressure plate works in conjunction with the upper heating plate to complete the four-sided heat sealing. The cutting mechanism is located downstream of the heat-sealing mechanism and includes a pair of conveying rollers, a longitudinal cutting mechanism, and a transverse cutting mechanism. The pair of conveying rollers are mounted on the frame, and a drive motor is installed on the frame to drive the conveying rollers and pull the continuous packaging body that has been heat-sealed. The longitudinal cutting mechanism is mounted on the frame between the conveying rollers and the heat-sealing mechanism and is used to cut along the longitudinal direction of the packaging body. The transverse cutting mechanism is mounted at the rear end of the conveying rollers and is used to cut the continuous packaging body laterally to finally obtain individual plaster packaging bags.

[0006] The plaster packaging machine and its production apparatus obtained by this utility model have the following advantages: the conveyor belt and its limiting protrusions enable precise, equidistant, and continuous material conveying; the compact layout of the upper and lower film unwinding and pressure rollers allows for seamless connection between material compounding and conveying, reducing the transfer and positioning links in traditional processes; the heat sealing mechanism adopts a precision linear module driven by a servo motor, combined with a heating plate with multiple rows of rectangular annular protrusions and a pressure plate controlled by a cylinder, which can perform four-sided heat sealing on the conveyed material, greatly simplifying the process flow; finally, in conjunction with downstream longitudinal and transverse cutting, this equipment can integrate continuous production, precise heat sealing, and efficient cutting into a smooth production line, effectively improving production speed.
